I think it more the steps than the presentation. That why i added the other one.
3-4(5*4)=-77
3-4(20)
3-80
3-4(5*4)=-20
3-4(20)
-1(20)
If you thought of solving thru each parts. Not ever one remembers PEMDAS or please eat my diarrheic ass snatch. sad to say people won't remember or never were taught it. I remember it as the foil method of First, Outer, Inner, Last.
The problem is that a lot of people absolutely remember PEMDAS but it's a shitty way to learn it because all people remember is PEMDAS.
So they literally take it has Parenthesis then Exponents then Multiplication then Division then Addition then Subtraction. Which is wrong.
It's why so many people are literally getting this problem wrong. Because the concept of multiplication and division being the same function baffles their mind.
Honestly, it's all about how the problem is presented.
(6/2)/(1+2)
is the same problem as
6/2(1+2)
but it's easy to see it as :6/((2*(1+2))
It's somewhat outdated but I guess when people see the division sign, it's become everything to the left of it will be a numerator, everything to the right will be a denominator sort deal?
I made a calculator in my CS class that dealt with stacks and hierarchies of this sort so this comes naturally for me, but I definitely could see why people would make the mistake.
If you read the comments, it's clear it's not any issue of the people misreading the problem itself. It's a problem of Order of Operations either being taught wrong or learned wrong by way too many people.
